3 Claims.

This invention relates to apparatus and method for applying a germicide or insecticide.

An object of the invention is to provide apparatus, or a spray gun, which is simple in con- 5 struction, durable in service and easy of operation to apply by compressed air or steam liquid germicide or insecticide.

A further object of the an improved method for micide and insecticide and in reaching remote parts general usefulness.

Other objects will be apparent from the following detail description of the invention and of the specific embodiment illustrated in the drawing.

Fig. l is a plan view of the device;

Fig. 2, is an elevation at the discharge end oi' the device;

Fig. 3 is a side elevation partly in section; and

Fig. 4 is a detail sectional view.

Apparatus embodying the invention and specifically illustrated in the drawing include a base I adapted to engage the wall of a container 2; a straight tubular barrel 3 integrally connected with and supported by the base I through a portion 4; a tubular nozzle 5 spaced from the inner walls of the barrel 3 by ribs 6 and its outlet discharging within the barrel a substantial distance from an outlet 1 of the barrel to form a mixing chamber 8; a nipple 9 formed on the inlet end of the barrel and adapted to telescope within a pressure hose; a tube III supported by the base 4, as shown in Figs. 3 and 4, and extending with- 35 in the container 2; and a conduit II connecting the tube I0 with the opening in the nozzle 5 and controlled by a valve I2, which has a head I3 so positioned that it may be manipulated by the fingers of a hand engaging a handle I4 which is supported by members I5. attached to or, as shown invention is to provide applying a liquid gerwhich will be effective of a room, and in its in the drawing, integral with the barrel 3. One

or more helical ribs I6 may be formed on the outside of the nozzle 5 to give a swirl to compressed air or steam passing through the barrel 3 and within the chamber 8 to mix the materials.

It has been found that a liquid germicide, such as a chlorine solution, may be effectively applied by compressed air or steam under substantially high pressure where the liquid is thoroughly mixed with the gas. The same is true with an insecticide, such as a fly spray. l'In both cases steam is moreefi'ective than air.

The foregoing is a summary description of the device illustrated in the accompanying drawing,

while the essential features of the invention are pointed out in the appended claims. A more detail description of the invention and of the vembodiment shown will assist in understanding and practicing the invention. 5

'Ihe base I, as stated, is formed to engage the walls of a container. In the illustrated embodiment it is formed to engage the opening of a glass jar of familiar construction, having a clamp I1, which may be secured over the base as clearly 10 illustrated. It will be understood, of course, that the base I may be formed with screw threads to engage a container having screw threads at its outlet, or otherwise formed as desired, the particular attaching means being no part of this in- 15 vention.

'I'he base I, barrel 3, connecting member 4, nozzle 5, and handle members I5 may be cast integrally. The channel II may be bored through the device to communicate the nozzle 5 with the 20 tube I 0. The tube I0 is secured, as shown, by screw threads in an enlarged portion I8 of the channel II. 'I'he upper portion of the bore, which includes the channel Il, is enlarged and screw threaded to receive the shank of the valve mem- 25 ber I2. 'I'he inlet end ofthe nozzle 5 is pointed, as shown at I9, to reduce back pressure.

It will be understood that the passage of gas steam is used with a chlorine solution a moist spray results effectively treating the atmosphere and reaching remote parts of a room and any roughened or unevened portions of the wall. The 45 steam condenses on the wall in iine droplets in which condition it is most effective.

In applying a fly spray with steam, the heat and pressure put the ies on the Wing and the misty rspray is able to more effectively reach 50 the under portion of the wings of the flies, which portion is necessary to be reached.

It is obvious that various changes may be made in the details of construction of the device, within the scope of the appended claims, with- 55 out departing from the spirit of this invention.

We claim:

1. A spray gun for germicide and the like including a barrel having an in let connection for pressure hose and an outlet, a tubular nozzle within the barrel spaced from the inner walls of the barrel and opening a substantial distance from said outlet to form a mixing chamber, a base member supporting the barrel and adapted to engage the walls of a container, a tube adapted to extend into the container upon which the base is placed, a valve for opening the tube to the nozzle, and one o'r more angularly disposed bailies adjacent the nozzle for causing a swirl in the mixing chamber.

24A spray gun for germicide and the like including a barrel having an inlet connection for pressure hose and an outlet, a tubular nozzle within the barrel spaced from the inner walls of the barrel and opening a substantial distance from said outlet to form a mixing chamber, a base member supporting the barrel and adapted to engage the walls oi a container, a tube adapted to extend into the container upon which the base is placed, a valve for opening the tube to thenozzle, and a helical rib on the nozzle adapted to cause a swirl within the mixing chamber.

3. A spray gim for germicide and the like in- 5 cluding a base member adapted to engage the walls of a containenal tubular barrel supported by and above the base having at one end a connection for a pressure hose and at the other end an outlet, a tubular nozzle within the barrel and 10 spaced from the inner walls ot the barrel, a handle connected with, parallel to and above the barrel, a tube supported by the hase and extending within a container upon which the base is placed, a conduit connecting the nozzle with 15 the tube, and a valve member extending laterally into the barrel, adapted to close said conduit and having manual engageable means thereon adjacent the barrel and below the handle so positioned as to be operable by the ngers of a 20 hand engaging the handle.
